- The current slew rate can be changed continuously in constant current and constant resistance modes
- Supports 0-V input – an indispensable feature for testing single-cell fuel cells
- Individual units (channels) can operate either independently or in synchronization
- Up to 5 load units of the same model can be operated in parallel
- Up to three values can be stored in memory for each most frequently used operation mode and range
- Equipped with various types of protection circuits: Over Voltage Protection(OVP), Over Current Protection(OCP), Over Power Protection(OPP), Over Heat Protection(OHP), Under Voltage Protection(UVP), And Reverse Connection Protection(REV)
- GPIB/RS232C are standard interface
- External control is available to turn on or off the output

Description:
The PLZ-U Series provides a set of compact, high-performance multi-channel electric laoad systems capable of operating in three modes - constant current, cconstant resistance and constant voltage. Adopting the modular (plug-in) design, the Series consists of four models - two frame models and two load unit models. The PLZ-30F frame can configure the load units up to three channels, and the PLZ-50F frame can configure up to five channels. Two load unit models are available, the PLZ-70UA (75-watt load that operates even at 0 V) and PLZ-150U (150-watt load that operates from 1.5 V up). Load units can be operated in parallel to increase the current capacity or power capacity. By combining different models of load units and frame, the power capacity can be changed from 75 W to 750 W (when five PLZ150U units are mounted in a PLZ-50F-frame). Supporting the GPIB and RS-232C interfaces as standard, the electronic load can be built into various types of test systems, making it useful in testing fuel cells, secondary cells, DC/DC converters, switching power supplies, multiple-output power supplies and more. Both interfaces support IEEE 488.2 as well as the Standard Commands for Programmable Instruments (SCPI) commands, developed for testing and measuring instruments. |
